- Investment Season 4: Eastern Wave is now live
- Five new Grade 25 vessels join the fleet
- Special autumn events continue throughout October
After exploring the recently added Production feature, Line Games has unveiled a new chapter for Uncharted Waters Origin with Investment Season 4: Eastern Wave. This season, inspired by legendary Ming Dynasty explorer Zheng He, will continue until December 14th.
In Uncharted Waters Origin's fourth season, you'll venture into the South China Sea, focusing on key ports like Quanzhou and Macau. Here, you can trade for exclusive commodities such as giraffes, rare fabrics, textiles, and livestock.
A new Great Adventure activity has also been introduced. Each day, geographic coordinates sent to your in-game mailbox will guide you to Land Exploration sites. Completing these adventures rewards you with Season Investment Certificates and the new Grade 25 Build Request, which is crucial for ship construction.
This season introduces five Grade 25 ships to the fleet: the Large Corvette, Soleil Royal, San Felipe, Large Fu Ship, and Djong. To build these ships, you'll require Grade 25 materials along with either a Grade 25 Build Request or an upgraded Grade 24 vessel.

Additionally, the Mate Transcendence system now offers a Stage 2 upgrade. Admirals and Mates who have already completed Stage 1 can gain an extra +40 levels in total. For similar adventures, explore our selection of the top mobile sandbox games.
Autumn celebrations bring even more incentives to sail. Until October 28th, the Fall Leaves 14-Day Attendance Event provides seasonal chests containing valuable rewards like S Grade Common Contracts and Enhance Protectants for all players.
Seasonal crafting recipes are back, allowing you to make traditional treats such as Songpyeon, Mooncakes, Dango, and Roasted Chestnuts. Consuming these items grants Fallen Leaf Tokens, which can be traded for growth materials and the new Transcendent Token required for Stage 2 upgrades.
Finally, don't miss the Full Moon 7-Day Attendance Event starting October 3rd, and the Moon Festival Production Relief Event available until October 12th, which reduces recipe requirements for time-limited crafting.
